Release Notes srn004
PSoC Express Version Release
Release Date: December 2005 Thank your interest PSoCExpress. information this document lists installation requirements describes software updates changes related Version 2.0.
Updates Everything about PSoC Express found aware there also Beta version site where updates that Beta Release found, which Cypress Semiconductor Corp. software (including PSoC Express software) maintained company repository. Check http://www.cypress.com/ under Design Resources Software Drivers, where list Cypress software drivers appears.
System Requirements Recommendations System Requirement Processor Speed Free Hard Drive Space Screen Resolution CD-ROM Drive Port, preferably Open Host Controller Universal Serial Port Windows® 2000, (SP1) Microsoft Internet Explorer (SP1) Adobe Reader (For Viewing .pdf Documentation) Minimum 1024x768 Recommended 1280x1024
Installation CHOOSE "REPAIR" OPTION WHEN INSTALLING ITEMS. HAVE PREVIOUS INSTALLATION ITEM, FIRST TIME EXECUTE INSTALLATION PROGRAM WILL REMOVING VERSION. EXECUTE SAME INSTALLATION PROGRAM SECOND TIME INSTALL VERSION. Install PSoC Express 2.0. Install version PSoC Programmer least 1.17).
PSoC Express DOES require PSoC Designer, will interfere with existing PSoC Designer installation. information updating PSoC Designer viewing editing PSoC Express-generated projects, "PSoC Express Version 2.0: Installation" document CD-ROM www.cypress.com/psocexpress. these items have been installed previously with older version, choose remove them when executing item's installation program, then re-run installation program install version. PSoC tools must installed parallel each other (same disk, same directory). tools installed individually, user must ensure that they directory, parallel each other. Limitations
NOTE: Designs built with version guaranteed compatible with version 2.0. recommended that work with copy when attempting open project built with version even earlier beta 2.0). necessary (and highly recommended) that build design fresh rather than attempt migrate from earlier version.
PSoC Express single compile engine, which prevents multiple simultaneous "Build" operations. attempt "Build" more than PSoC Express project time (although more than project/instance open time). Underscore character ("_") allowed name objects. try, program will prevent from completing step until remove underscore. reserved words name objects. Reserved words are: C-Language reserved words, PSoC Express reserved words state names defined design (under user control). undetected GUI, this will result build error, indicating offending name error messages. PSoC Express automatically detects needed hardware resources matches appropriate PSoC device when "Build" selected. resource manager cannot detect when exceeded. build error occurs, user should also build project largest PSoC device order isolate this possibility. PSoC Programmer installed does appear when "Program" selected appears disappears, remove connected PSoC programming devices from computer then re-connect them. PSoC Programmer still operating, shutdown computer restart. valid project must consist least input output device. Selection interface and/or valuator only will correctly build. input output then choose "Build." objects with discrete states (LED with OFF, example) should always their named states when setting state comparing current state. This will ensure portability design regardless particular device's property setting. Additionally, simulation following (Input_1) Then does work properly JavaScript characteristics. generated PSoC firmware will perform expected, according language guidelines, simulation will reflect this behavior.

ensure consistent simulated generated code, explicit comparisons with object's named states (select "Expression Assistant" dialog that supports expressions complete list names). Some devices must selected instantiated (select catalog click property settings available (Tachometer inputs example). expected choices when selecting device, complete catalog selection (click then right-mouse-click choose "Properties" complete property list. When defining custom states Valuator Output, have first define states, save transfer function then choose edit order states visible Expression Assistant. Stimulus file inputs range checked will shown numerically entered simulation widget, graphical widget position bound driver's range. user's responsibility ensure proper input range within stimulus file. Simulation PSoC Express implemented with JavaScript. Boolean expressions, such (Input_1 33), cannot themselves assigned output JavaScript. poor design practice this, even firmware, lead avoidable bugs. Expressions perform range checking signed integer values, limiting them from -32767 32767. Octal values (0777, instance) hexadecimal values (0x4343, instance) range checked valid bits. They will truncated PSoC firmware (but simulation will truncate them). Expressions contain value valid 16-bit signed integer "-32768," because application prevents alternative enter "0x8000," which equal "-32768" bit. Byte values promoted integer type math operations which types expression byte. least Continuous type Valuator (16-bit signed integer) must used prevent overflow addition operations. When entering complex combinatorial expressions, Build failure occur long line lengths handled correctly compiler parser. solution split complex involved combinational logic lines into multiple lines (Status Encoder Transfer Function well suited this). conversion utility Schematic report requires installation Java Runtime engine, follow prompts during first-time execution "Print PDF" install JRE. conversion operation trigger warning from antivirus software agent. Enable script during this operation conversion will succeed. schematic entries associated with master (LM75, Slave instances) will have required pull-up resistors missing from note appears schematic indicating need pull-up resistors value required). Interface Valuators allow input from outside system explicitly range checked/limited. include these your system input Table Lookup Transfer Function, cause random behavior. Instead, define another Valuator define Transfer Function perform range checking limiting.

Simulation Firmware match exactly with respect integer math results. JavaScript performs floating-point math PSoC performs strict integer math. simulation should only used guideline integer math results. User assignment requires PSoC Express code generation engine auto-place route functional blocks within PSoC. order pins assigned manually combination functions sometime make assignment fail, even autoassignment mode. workaround which drivers getting assigned (what type), drag drivers pins, first place pins which succeed, then auto-place rest. experience difficulty assigning pins, that part shown large enough (enough pins internal buses) functions. (External Watchdog drivers when used large number conjunction with Tachometer drivers show this tendency particular). workaround, choose device same family with more pins then larger family (higher part number) with more pins more resources.
Errata Changing valuator transfer function from State Machine other type transfer function will work correctly. This only happen have valuator with State Machine transfer function that been automatically torn down, indicated "Impact Analysis." dialog (due dependent change, like when inputs been deleted), then choose different transfer function type upon rebuilding NOTE: This result build error. Changing valuator transfer function State Machine from other type transfer function will work correctly (but allowed GUI). Instead, must delete original valuator choose valuator, selecting State Machine transfer function. NOTE: This result build error. possible error that says "Unable save project" even when valid project name/location used. this occurs, select "OK" proceed, then save project under name.
